MANUFACTURE Y OF COLLAPSIBLE TUBES.-

Applieation .led January 6, 1923.

T all fui/wm t may concern:

Be it known that I, VVALTI-rnn KALB, a citizen of Germany, and residentof the city of lieipZiO, Germany, have invented certain newand usefulImprovements in the Manufacture of Collapsible rIlubes (for which I haveled an application in Germany, August 25, 1921, Serial K. 78,888 XII81C), of which the following is a specification.

This invention has reference to flexible or collapsible tubes such asare commonly used for the containing and dispensing of semi-liquid,viscid or liquid, powderous, or other material in a great variety ofmechanical and chemical arts, and it is particularly intended to improvethe construetion and manipulation of containers of the hind mentionedand to reduce the costs of manufacture thereof. In the tube according tomy invention the delivery aperture cf the tube is controlled by a freelymovable closing member in the interior of the tube which is actuated bya spring member, preferably a piece of spring wire in operative l5engagement with said movable closing member, and the free ends of whichare disposed to become engaged with or below suitable projections,shoulders or stops arranged at the inner walls of the tube, andpreferably in the vicinity of the delivery opening thereof. 'Ihe saidclosing` member which may be of globular, oval, conical, bar-like, orany other suitable shape is held against the aperture of the tube by theoperation of the spring-actuating member, and is withdrawn from saidaperture upon the compression of the tube by the pressure of thecontents thereof around and against said closing member and the marginalaperture enclosing portions of the tube.

In the manufacture of the tube and the closing member hereinbeforereferred to it is preferable to manufacture the body of the tube and thehead portion thereof as a Ai5 unitin one piece, ordinarily by subjectinga metal disk to a. drawing operation, and by this means the bearingmember for the closure and the shoulders, projections, or abutments forthe spring-actuating member should preferably be manufactured in acontinuous stage of operation. The closing member should then beinserted from the outside into the aperture of the tube, and

Serial No.' 611,127.

'is then connected withy the spring member while the latter is undertension.

In case the body of the tube and the head section thereof are integalwith each other, the point of connection of the spring member and theclosing member is not accessible from' the outside, so that, underordinary conditions, the positioning of said spring member and itsconnection with the closing member are rather ditlicult to produce. Inaccordance with my invention this diiiicu-lty is overcome, and a mostperfect connection of said two members is obtained in an easy and rapidmanner by providing -a support for the spring member, and thentelescopingly mountingthe closing member with its fork shaped lowerportion, and the tube which has been previously provided with theshoulders or project-ions referred to upon said, preferably axiallydisposed support, until said spring member with its freely exposed endshas become engaged by this movement with the recessed lower portion ofthe closure, and the spring has been put under tension, whereupon saidspring member by the compression of the fork shaped ends ofthe closureby means of a kind of pincers or the like,v is securely connected at theinterior of the tube with the closure in the closing position of thesame.

By proceeding in this manner the connection of the closing and thespring actuating members may be effected in not more than two stages ofoperation. In order to further facilitate. and simplify the course ofmanufacture, and to overcome the necessity of another stage of operationthe said supporting member in accordance with my invention isconstituted by a hollow body which is displaceably mounted upon arelatively stationary mandrel, and which is provided moreover with apair of tongs, pincers or the like engageable with the spring member,the jaws of said tongs being adapted to compress the legs of the forkshaped lower portion of the closure upon the depression of the hollowsupporting member. The tensioning of the spring member, its introductioninto the closing member, and the connecting of the two members iseffected in a single operation in accordance with my invention. Providedonly separate projections on the inner wall of the tube are employed assupporting abutments for the free spring acting ends of thespring-actuating member, the perfect engagement of the spring with theabutments during the mounting of the tube is insured by providing thehollow supporting member with recesses or grooves for engagement withsaid abutments upon the mounting of the head of the tube upon saidsupporting member, the spring being secured in position in a slot of thesupport in the connecting line of said recesses. Thus the tube with theprojections or abutments is positively guided, so as to become engagedwith the ends of the spring. Any possibility of the dropping ofi of thesometimes very light and thin spring wire may be further prevented byproviding a retaining magnet for the spring upon the support between therecessed or grooved portions thereof.

rIhe downward movement of the tube which operates the connection of theclosing member with the spring may also be utilized in accordance withmy invention for the, preferably simultaneously effected, cutting offthe desired length of the tube.

Inasmuch as a thin piece of steel wire or the like which may constitutethe spring-actuating member above referred to, can only be seized withdifheulty, and is not very readily positioned upon the support by hand,means are provided according to my invention for the feeding of thespring wire to the support from the wire staple, and for mounting thespring upon the support. With this end in view a sliding carriage isprovided laterally of the means for connecting the closure with thespring member, and upon a carrier provided with clamping or holdingmeans for the spring wire delivered by the wire staple, the feeding ofthe carriage causing the therefrom projecting length of the spring wirewhich latter is retained by suitable clamping means on the carriage, tobe pushed upon the supporting surface of the supporting members, whileupon the return stroke of the cariiage the spring wire is retained bythe clamping means on the supporting carrier and the clamping member ofthe sliding carriage is caused to slide past the wire. rlhe slidingcarriage therefore acts as the means for the feeding and positioning ofthe spring.

If the carriage would be guided merely at a right angle to thesupporting member or mandrel referred to, the length of spring wireprojecting beyond the carriage would be disposed close to the saidsupporting member, which would interfere with the mounting of the tubeupon said supporting member. This difhculty may be obviated according tomy invention by providing for the turning of the carrier for thecarriage upon the return stroke, by which means the spring wire becomesinclined with relation to the supporting member. In this position thespace between the projecting length of spring wire and the supportingmember is sufficiently large to allow of the unimpeded pushing ormounting of the tube.L

The invention will be more fully described with reference to theaccompanying drawing, showing by way of example, aI machine embodyingthe principles of my invention. Figure 1 is a longitudinal sectionthrough a device, showing the manner of connecting the closing memberwith the spring, and the cutting off member for the cutting and trimmingof the tube body. Fig. 2 is a side view of a portion of Fig. 1. In Fig.3 I have shown the device in longitudinal section in accordance withFig. 1, but in a different operating position. Fig. 4 is a plan view ofpart of Fig. 1, and Fig. 5 is a similar plan view of Fig. 3. In Fig. 6the supporting member is shown in top plan view and on an enlargedscale. Fig. 7 is a longitudinal sectional view through the upper portionof the supporting member on the line 7-7 of Fig. 6; and F ig. 8 is asimilar section on the line 8-8 of Fig. 6. In Fig. 9 I have shown inlongitudinal section atube, such as may for instance be obtained by thedevice according to this invention. Fig. 10 is a side view of the meansfor the feeding and positioning of the spring upon the supportingmember. Fig. 1l is a view similar to Fig. 10, but in a. differentoperative position. Fig. 12 is a. front elevation, and Fig. 13 is a planview of Fig. l0.

As shown in the drawing the body 1 of the tube which is here representedas being integral with the tube head 2 (Fig. 9) is obtained in theordinary manner from a metal disk by a drawing operation in a tubedrawing press. The tube head is provided with projections or annular orotherwise disposed shoulders serving as stops or abutments for the endsof the spring 3, the said shoulders in the form of construction shown byway of example in the drawing being constituted by two inwardly directedprojections f1. The tube head 2 is, moreover, provided at the apertureof the tube with the seat F which operates both as a tightening andpacking member as well as cutting or severing means for the contents ofthe tube discharged from said aperture. The seating surface 5 may bestrengthened and increased by rib-like staysI or fins 6, the inwardlydil rected surfaces 7 of which are made to conform to the seatingsurface of the closing member, in order to obviate the cutting of theclosing member by the sharp edges of the aperture of the tube. Theclosing member itself in the form of construction herein shown comprisesa conical valve 8 with a cylindrical shank 9 which may be easilymanufactured in large quantities by means of a rivet press or a similarmachine. The shank 9 is fork-shaped with two legs 10.

means thespring is eonnectedto the clamp-g 1'25' lil the cutting edges36 of the knives 35 impinge at first upon the tube body 1 project-l ingbeyond the enlargement 40 and produceV anincision, whereupon by a kindof shearing action a ring is graduallycut off fromY the tube body insuch a manner that the'said: tubebody-which, as `manufactured in'A the'drawing press vor theflike, is mostly of un-4 equal length at its [endsis evenly `out off.,` The' lrnives 35,f37 i' during thisfprdc'edure en-'gage belowI the 'enlargement :40,''and by" meansfof the knives 37 out:ofi| ring or annulus is ripped open in two halves in the longitudinalvdirection V"of the tube, said :t halves dropping ofi' laterally fromthe ref duced portion '41, so as not to interfere with the mounting ofthe following tube. Upon releasing thevtube after' the depression -ofthe hollow mandrel 19 the knives" 35,37, and the mandrel 419 are'returnedto their initialposition bythe action of the spring, 16,while-fthe jaws 26 are rockedQbaclr into` the open position by gravityYaction.

If it isfdesired to manufactureganotheiY size of collapsible tube havinga shorter body portionfl, it is necessary to bring.;y the low er`portionI of thebody into operatingfreach ofi the knives' 3 5, 37; For`this purpose itisf only'znecessary to "remove .thelcorrespondingintermediate piecesZS()y lfrom""around the stationarymandrel 12,' and between v tlie" "'1'nz in' drel and the head portionand also' to v remove the corresponding insertion Aor in` termediatepieces .32 from the hollow man-r4 drel-19.

so thatvthe lower part of the lshorter tube` body 1 projects beyond theenlargement40,

and lmay becut off upon the V'depression of .the hollow mandrel 19.

Now as "regards-- hel mserton'of the wire l member 3 and 4feeding tothe'supporting' mandrel `i 19 and its positioning in` the slot 2, thismay befeifected' bythe parts of the machine, 'as shown particularlyinFigs. l() to'13 .of the accompanying drawing. As shown in thesefigures` a guide 42 is 'prof vided on the frame 11 of the machine forcooperation with an anvil 43 which may bel actuated for instance bymeans of atreadle by the operator who attends tothe mountingandtreatment of the collapsible tube, or .byfma'chinery or by any other.equivalent means, properly'timed to cooperatewith thev above describedtreatment of the collapsible tube."' .l

The upper end 44 of the anvil 43 and the upper end 45 of the guide 42are detachably arranged, in order to beV able to adapt'the 'wire feedingmeans to the particular rela-'l tive position of vthe hollow mandrel 19the manufacture of different sizes of tubes, the parts 44 and 45 beingfor instance exchanged against corresponding parts of differentoperating length, or the said parts may be of shorter length, and may bemadek adjustable by suitable guides, screws and the like, not shown inthe drawing, andop-I eratmg inv an obvious manner.y Upon the;

part 45 of the guide 42 a supporting carrier 46 is secured in which acarrier 49 is pivot` ally mounted on a stud 47 between the eyes 48 onthe support 46. :At both sidesof the eyes 48 twoyarmed levers "are'pivotally mounted on, the studf47 The arms l59 "of said levers areconnected by across piece 5 1@ engage'bctwe'en the stop pins '55 ofthecarf' ria-ge 56 guided on the carrier 49, andmov# able in the directionVof the mandrel 19." Upon the carrier 49 clamping and 'straight-.

with -an adjustable delinite clamping`p1essure by a spring 64.Laterallyofthe cari rierf49 the tongs 60 are provided with two stops 65which cooperate with stop pins 66 on the carrier.` "Ihe rocking movementof the carrier 49 towards thel mandrel 19 is limited by the engagementof its abutting surface. 67 against a stop 68 providedlon the support46, y'while upon the 'rockingmovement of the carrier49 inthe oppositedirection away from the mandrel 19 the carriage 56 engages by'fitsabutting surface 69 with a stop 7 O,

of the carrier 49 spring 71 is provided to insure .the constantengagement of the'1 arms 54 ofthe'two-armed levers 5 0, 54 with fthestop pins 55 of the carriagef56, the said spring. tending tolclraw thecarrier 49 alwayswtowards the mandrel A19. This part of the machineoperates substantially as fol- Alows: 'l[n the released 'position of theanvil '43theftwo armed levers 50, 54 and the car#y position shownin Fig.l1`of"the"'drawing,

the upper surface of the carriage 56 being downwardly inclinedrelatively to the mandrel. The spring wire 57 projects beyond the frontedge of the carriage to such an eX- tent as to present the length of thespring 3 to be connected to the Aclosingy member 8, 9. Upon now forcingthe anvil upwards it impinges against thevcross piece 51, and rocksthetwo-armed levers 59, 54 towards the mandrel 19, while placing thespring 53 under tension. By the engagement of the arms 54 with the stoppins 55 the carriage 56 is first fed forward, and at the same time thecarrier 49 is rocked on the shaft 47 under the action of the spring 71,until the abutting surface 67 of the carrier becomes engaged with thelug 68. The wire supporting surface of the carriage 56 is then at thelevel of the slot 22 in the head 26 of the hollow mandrel 19 (Fig. 10).The carriage then proceeds on its forward feeding movement, while theprojecting portion?) of the spring wire is pushedV into the slot 22.Then the spring 3 is disposed in the desired position the stops 66impinge against the stop members of the pincers 60, and by means of thepincher-like cooperation of the edge 63 of the carriage 56 with thecutting edge of the tongs or pincers 60 the wire is cut off. During thisforward feeding movement of the carriage 56 the spring wire 57 has beenpushed forward for the amount of one wire length 3, because the spring64 forces the tongs 60 upon the spring wire 57 with suliicient force toovercome the clamping pressure at the rollers of the clamping device 58,59. Upon now releasing the anvil 43- the carriage 56 under the action ofthe spring 53 is rocked away from the mandrel 19, until its abuttingsurface 69 engages with the stop 70 of the carrier 49, and forces thecarrier back into the position shown in Fig. 11. In this position thewire supporting surface of the carriage 56 is inclined with relationtothe mandrel 19. At this return stroke of the carriage 56 the springwire 57 has remained stationary with relation to the carrier 49, becauseit is prevented from moving backwards by the clamping pressure of theclamping rollers 58, 59, the tongs 60 sliding loosely past the wire.Thus, in the position according to Fig. 11 the spring wire 57 projectsfrom the edge 63 of theY feeding carriage 56 for the length of thespring wire member 8. In consequence of the inclined position of thecarrier 49 the distance between the end of the spring wire and themandrel 19 is comparatively large, so that the tube 1, 2 may be placedupon the mandrel 19 without any impedimentl whatever, so as to be ableto connect the spring 3 which has been introduced into the slot 22 inthe manner described and by the instrumentalities referred to withl theclosinginember 8,91

It istherefore obvious that for the feeding and the positioning of thespring 3 in the slot 22 vof the hollow mandrel 19, only a singlemovement of the foot of the operator is necessary, if the machine is tobe operated by the workman. The operator after the insertion of thespring member 3 pushes the tube furnished by the drawing machine, andwhich has been previously provided with the closing member upon thesupporting mandrel 19, and then by the depression of the mandrel effectsthe connection of the spring 3 with the closing member, while at thesame time the body of the tube is cut off straight to the requiredlength. rl`he tube manufactured in this manner in practically only threeoperating stages, aside from the separate manufacture of the closingmember 8, 9 is shown in Fig. A9 of the drawing.

For the manufacture of another size of tubes with shorter body, theteminal portion 44 of the anvil 43, and the guide 45 of the part 42 maybe screwed off, and may be replaced by corresponding parts of suchstructural height that in the position of the device corresponding toFig. 10 the wire fastening surface of the carriage 56 is at the samelevel with the slot 22 in the head 2O of the hollow mandrel 19 whichlatter in its turn has been lowered by the taking` out of intermediatepieces 30 and 32 as above described.

Thc invention is susceptible of various other alterations andmodilications to more fully adapt the same to varying conditions ofapplication and to the convenience of the user, and within the scope ofmy invention. The invention is broadly applicable to the mounting of anoutwardly displaceable closure in tube-like or other containers, and itis not restricted to containers with collapsible or foldable walls only;nor is the shape of the closing member of material importance, and thetensioning of the spring member and the trimming of the free end of the`container may also be produced by moving said instrumentalities towardsand in the direction of the closing member, and it is evident thatinstead of manually the device may also be operated by machinery.
